Hyper-V – VM’s page file on SCSI VHD

Just a heads up if you get an warning windows could not create page file on specified volume. This is because the SCSI disks in Hyper-V are driver based and are loaded after windows loads. This would mean the page file would be loaded first before the disk was mounted. As of Windows 2008 R2 Hyper-V this doesn’t not seem to be supported. If you switch your page file VHD to a IDE drive it will solve this issue.
